The ones I've seen have the Z-link in the right side, and both links pointing forward and upward on the left. This gives them huge amounts of rear-steer when the body rolls, which I assume is what they're trying to achieve by setting it up that way.



If I ever get around to building something crazy just for the sake of trying out some of my goofy theories, I'd like to set up a car with birdcages both sets of upper frame brackets... set it for lots of rear-steer for autocross, and flip the upper link to keep the axle straight for road course and drag racing, and do 2 separate adjustable sliding upper links for accell and braking forces.
